INTEBKAL-CdMBUSTIdN-ENGINE VALVE.

Application filed September 12, 1921'. Serial No. 500,029.

and exact description or the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide a construction of valves peculiarly adapted 1: 2o internal combustion engines having a plu- Iality of cylinders and wherein the valveoonsists or an assembly in a practical and durable form of a plurality of valve bodies or sections or units, corresponding in construction and adapted to be separately constructed and independently removed for repair or replacementbut mutually or jointly operated and held in roper position in relation to the ports which they control and which may be efiiciently lubricated throughout bv means provided for a continuous circulation of oil progressing longitudinally of the series of separable bodies or sections; and in that connection to provide improved so and eflficient means for assembling and holding the valve bodies or sections in their proper relative position and for bodily adjusting the same and maintaining them in proper position While facilitating the dismounting or removal thereof when required for cleaning or repair; and with these ohfacts in view the invention consists in a construction, combination and relation of parts of which a typical embodiment is illustrated in the accompanying drawing, wherein:

Figure 1 is a sectional view of a portion of an internal combustion engine provided with a valve mechanism embodyingthe inventi0n.,-'

respectively of opposite end portions of the valve mec amsm.

Figures 2 and 3 are enlarged detail views Figure 6 is a longitudinal sectional view of one of the valve members.

Figure 7 is a side view of one of the valve members.

Within a suitable casing 10 which may be water jacketed as indicated at 11 with an outlet 12 is arranged the valve comprisin in the construction illustrated a plura ity of valve bodies or members 13 havin the ports 14 and-operating in a tapered va ve sleeve 15, said valve bodies or members being secured together in series for simultaneous movement through any suitable or preferred mechanism such as that indicated by the gear 16 carried by the spindle 17 at one end of the series.

Fitted in suitable grooves orseats '18 disposed longitudinally of each valve member or section at opposite sides of the terminals of the ports 14 therein are packing strips 19 to which an outward impulse is imparted by expansion'rings 20 fitted in channels 21 which are accessible from the terminals of the valve members or sections, thrust pins 22 being arranged to convey the expansive force of the rings to the said strips and being arranged in radial openings establishing communication between the seats 18 and the channels 21. These expansion rings are held in place by annular webs 23 on cap plates 24 fitted against the ends of the valve members or sections and also serving as retainers for packing rings 25 of the expansion type which are located at the extremities of the longitudinal packing strips 19.

The terminalsof the valve members or sections are provided with axial cavities 26, the outer cavities of the terminal valve members being adapted for the reception re spectively of the adjacent ends of the terminal spindle member '17 above described and a similar terminal spindle member 27, while between thohdjacent ends of the valve members or sections in the series and ter-' minally fitted in the cavities 26 thereof are the intermediate spindle members 28 forming coupling members between the valve members orsections and said terminal and intermediate spindle members are inter-' locked with the valve members or sections by means of keys or gibs 29 sothat rotary motion applied to the spindle member 17 at one end of the series is conveyed throughout the series, and all of said spindle mem bers are mounted in anti-friction bearings 30 of which one or-more may be located as shown between the adjacent ends of each two members or sections of the'valve with spindle member 27 is arranged a similar- -bearing ballor anti-friction thrust member 34 held in place by a spring 35 of which the tension is adjustable by means of the plug 36. Preferably however this plug 36 is capped to occupy a fixed position, and the spring 35 is held under tension by the adjustment of the plug 33 at the opposite end of the series, to insure a proper relative arrangement of the several elements comprising the valve and insure a proper operation thereof in use. i

Formed in the-bodies of the valve members or section are channels or ducts 37 terminally communicating with the cavities 26 in the extremities of the members or 'seetions, and the spindle members are hollow or tubular in. formso as to establish cominunication between the channels or ducts of the several valve members or sections, and. in communication with the terminal spindle members 2'! and formed in the casing of the valve is an oil supply port 38 with which may be connected an oil su ply tube or pipe (not shown) by means 0 which lubricating oil may. be supplied tothe valve under pressure and therefore adapt it to circulate throughout the entire series of elements comprising the valve to an outlet 39 at the opposite end of the series from which thesurplus may be conveyed back to the "source of supply or disposed of otherwise as may be preferred,.'the hollow portion 40 of the spindle members 17 being rovided with lateral ports 4.1 to permit 0 the escape of the oil to the outlet 39. Adjacent to the .ports' 41 are complemental baflling rings 42 and 43 of which the former, is carried by the terminal spindle member '17 and the' latter bythe casing and which serve to protect the terminal. anti-friction. bearing 30 said spindle'member 17against, undue pressure of theioilfwhich' would cause leakage into theihousing 44-which is preferably for.'the gearing by which the W1C}; is actuated and which also as shown may ut l zed; to support the ventilating tan, echanmmmdicatedat 45.

in this way the oilby which the valve in lubricated is kept out of the crank and separate from the oil in the latter In may be returned to the tank for repeated use in the valve, under pressure rt desired.

Having thus described thelnvention, what I'claim is:-

1. A valveyfor internal comlzvustioilen gines. consisting of a plurality of members or sections of'ported construction arranged in coaxial alignment and terminal and intermediate spindle members having terminal interlocking" conneotion with said valve members or sections, the spindle members being of tubular construction and the valve members or sections being provided with channels or ducts in communication withwthe bores of said-spindle members to establish ,a continuous lubricating conductor throughout the series, means being' provided for introducing and discharginglubricatin ,oil at the extremities" respec tively of t e series. i

3. A valve having members, a' spindle therefor andspanning,

ioo

a plurality of valve the'same and said valvemembrs'and spin-" I dle having communicating lubricant rpeasageways. i, v

LA valve consistingof a plurality of valve members, said members having cavi-, ties in adjacent ends thereof having a lubricant groove, 2, spindle extending into said cavities, and 'saidvalves having lubricanth grooves intermediate their axis and pe- .ripheries and in communication with said groove and the cavities. v v

5. A valvei'consisting of va-lve means,

spindle means therefor, adapted forfassa' bad:

of lubricant along the same, an means associated with said spindle [means to counteract the pressure. ofthe lubricant I of the spindle means;

6. A valve for internalbombustion having a'port therethrough and a channel in an end wall thereof, packing stripsarand prevent escape thereof longitudinally ranged on opposite sides of said portfan expans on ring in said channel, thrust pins extending from said expansion ringiaindengaging said packing strip, a cap havin i a web extending into said and a utting said expansion ring 3 sm'rounding t'hs valve and z'lappec .sy said cap plsis.

rotsiy valve for internal cpmbustior ngmss coinwising sspindle having a lubripssssge thsrsthz'ough, ported valve ,iemsers sssscistsd with the spindle in relativsly ssiation andprovided with lubricant passages communicating with the passage of s spindle, and. bearing means fer the spindle ss zweeii the valve members. 8; A misty valve for internal cembustion engines liming spaced valve members a,

In testimony whereof I afiix my signature in presence of two witnesses.
